TENTER-CHAIN.

Application filed July 13, 1915. Serial No. 39,641.

To all cl2/wm t may concern:

Be it kno-wn that I, l/VENDELL P. AN- THONY, a citizen of the United States, and resident of Ridley Park, Delaware county, State of Pennsylvania, have invented certain new and useful Improvements in rIenter-Chains, of which the following is a speciiication.

rlhis invention relates to tentering machines and more particularly to the chains which convey the cloth through the machine. v

1t has been the custon heretofore tomake the chains up of a series ,of links which are pivoted together and because of the great length of the chains the cost of manufacture has necessitated that the links be made of malleable iron and the cloth gripping surfaces of the links of brass plates secured to the links. The object of having the brass plates is Vtb avoid staining the cloth which would result from rust of the iron, if the cloth came in contact with an iron surface.

rllhe cost of links made entirely' of brass wouldV be prohibitive and therefore for the purpose of economy the iron links have been gener.- ally adopted. There has also been a considerable amount of machine work necessary in finishing the links and this has made them rather expensive even when made of iron.

It is the object of the present invention to provide a one-piece diecast link which will be made of a composition suitable for the purpose and will also eliminate the machine work which has been heretofore necessary in connection with the iron links.

A link embodying my invention is shown in the accompanying drawings, in which,

Figure 1 is a side elevation of the link; and

Fig. 2 is an end elevation thereof.

Referring to these drawings, 10 indicates the body of the link, which is provided with an opening 11 and a single ear 12 at one end and two ears 13 at the other end. rlhe ears 12 are adapted to enter the space betweenings' 14- and 15 in the ears. From the upper side of the body 10 there projects a substantially horizontal ledge 16 having a slot 17 therein. The upper surface 18 of the ledge 16 is the cloth gripping surface with which the gripper 19 cooperates. This gripper has the usual tail 20 and is connected with the spaced upwardly projecting arms 21 and 22 `by a pivot pin 23. The arms 21 and 22 eX-V tend over the ledge 16, as clearly shown in Fig. 2, and are integral with thebody 10.

The link,'as above described, is made by the die-casting process and all machining of lthe link is eliminated, the openings 14 and 15 and also the openings 24E for the pin 23 are formed in the casting in a manner well known to those skilled in thc die-casting art.

A link made in accordance with invention has all of the advantages of the ordinary form of link and can be produced at a fraction of the cost ofthe latter. The impreved link also has the advantage of being absolutely uniform throughout and all links made by the same dies are identical so that there will be no diiiculty in assembling the links. y y

Having described my invention what I claim and desire to secure by Letters-Patent A complete die-cast tenter chain link consisting of one piece only of non-rusting material andh'aving a cloth-gripping surface and spaced upwardly projecting arms eX- tending over said surface and provided with alined openinofsv for a gripper pivot.

' In testimony whereof l aiiX my signature.
